I shared this note with @OpenAI today. Onward!
Great conversation with Joel de la Garza on the @a16z podcast. We covered agentic security research with Aardvark, where AI and security are headed, and reflections on five-plus years @OpenAI. Thanks for having me! youtu.be/-clah3kPPHc

gpt-oss is out! we made an open model that performs at the level of o4-mini and runs on a high-end laptop (WTF!!) (and a smaller one that runs on a phone). super proud of the team; big triumph of technology.

What do you want to create next?
@MichaelKratsios Congratulations! Fantastic news.
@jaimeblascob @defcon @OpenAI It’s at 1050 tomorrow at the AIxCC Stage. Title is “Eating Our Own Dogfood” though I don’t believe the title made it onto the agenda.
I’ll also be recapping my and @marcnewlin’s escapades in the Spectrum Collaboration Challenge on a panel about @DARPA competitions at 1720 today.
Excited to give the closing keynote at the @BlackHatEvents AI Summit in one hour. Come learn about how we’re equipping the security team with LLMs @OpenAI.
